Vaccines are designed to give you immunity without the dangers of getting the disease. It’s common to experience some mild to moderate side effects when receiving vaccinations. This is because your immune system instructs your body to increase blood flow so more immune cells can circulate, and it ...raises your body temperature to kill the virus. Vaccines help protect us against disease and feeling mild or moderate side effects after receiving one is a sign that the vaccine and our immune system is working.

Tuberculosis (TB) is the leading cause of death from a single infectious agent even if is largely curable and
preventable. In 2019 an estimated 2.9 million of the 10 million people who fell ill with TB were not
diagnosed or reported to the World Health Organization1. The Politi...cal Declaration adopted by the United
Nations General Assembly in September 2018 commits, amongst others, to diagnosing and treating 40
million people with TB. In order to achieve these ambitious targets, there is an urgent need to deploy
strategies to improve diagnosis and initiation of care for people with TB. One of them is systematic
screening for TB disease, which is included in the End TB Strategy as a central component of its first pillar
to ensure early diagnosis for all with TB.

Since the launch of the 2012–2020 World Health Organization (WHO) road map for the control, elim-ination and eradication of neglected tropical diseases (NTDs) (1), considerable progress against NTDs has been made. Between 2010 and 2020, the number of people requiring interventions against NTDs glo...bally fell by 600 million, and 42 countries, areas and territories eliminated at least one NTD (2). In January 2021, a new NTD road map for 2021–2030 (2) was launched, setting future targets and mile-stones for 20 diseases and disease groups. The road map also sets cross-cutting targets, including for strengthened capacity of national health systems to deliver interventions through existing infrastructure.

The recently published World Health Organization (WHO) Strengthening infection prevention and control in primary care document collates existing standards, measurement and implementation approaches, and resources for infection prevention and control (IPC) in primary care. During its development, it ...became apparent that a number of already existing tools and resources have the potential to support facility-level implementation of IPC in primary care.
This toolkit brings together in one place a number of these tools and resources from WHO and other organizations, with a focus on those most relevant to primary care. These tools and resources have been compiled to support facility-level implementation in line with the recommended WHO IPC Hub and Task Force multimodal approach.

This report summarizes the latest scientific knowledge on the links between exposure to air pollution and adverse health effects in children. It is intended to inform and motivate individual and collective action by health care professionals to prevent damage to children’s health from exposure to ...air pollution.
Air pollution is a major environmental health threat. Exposure to fine particles in both the ambient environment and in the household causes about seven million premature deaths each year. Ambient air pollution alone imposes enormous costs on the global economy, amounting to more than US$ 5 trillion in total welfare losses in 2013.
This public health crisis is receiving more attention, but one critical aspect is often overlooked: how air pollution affects children in uniquely damaging ways. Recent data released by the World Health Organization (WHO) show that air pollution has a vast and terrible impact on child health and survival. Globally, 93% of all children live in environments with air pollution levels above the WHO guidelines (see the full report, Air pollution and child health: prescribing clean air. More than one in every four deaths of children under 5 years of age is directly or indirectly related to environmental risks. Both ambient air pollution and household air pollution contribute to respiratory tract infections that resulted in 543 000 deaths in children under the age of 5 years in 2016.

This guideline aims to improve the quality of essential, routine postnatal care for women and newborns with the ultimate goal of improving maternal and newborn health and well-being. It recognizes a “positive postnatal experience” as a significant end point for all women giving birth and their n...ewborns, laying the platform for improved short- and long-term health and well-being. A positive postnatal experience is defined as one in which women, newborns, partners, parents, caregivers and families receive information, reassurance and support in a consistent manner from motivated health workers; where a resourced and flexible health system recognizes the needs of women and babies, and respects their cultural context.
This is a consolidated guideline of new and existing recommendations on routine postnatal care for women and newborns receiving facility- or community-based postnatal care in any resource setting.

The Committee discussed the implications for preparedness for smallpox-like events reflected by the ongoing COVID-19 pandemic. The Committee noted how quickly diagnostics and vaccines could be developed and deployed when resources and political will were abundant. This rapidity was also due to the f...act that the genetic sequence of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) had been shared worldwide. It was noted that in one country SARS-CoV-2 had been reconstructed in a laboratory from the viral genome sequence before the first case of COVID-19 had been reported, highlighting the benefits of synthetic biology technologies for accelerated development of diagnostics as well as the oft-described potential risks. Lessons learned about clinical care during the COVID-19 pandemic were also discussed.

Cotonou Declaration oBuruli Ulcer
Cotonou, Benin, 30 March 2009
Neglected tropical diseases kill, weaken or incapacitate millions of people every year, causing permanent physical suffering, social stigmatization and reduced productive capacity. Buruli ulcer, one such disease, causes immense suffer...ing and disabilities, especially among children. Delayed schooling and loss of productivity are considerable among the affected populations. These adverse consequences tend to aggravate poverty in affected communities. Globally, the disease has been reported in 30 countries. In WHO’s African Region, Buruli ulcer has been confirmed in 12 countries and is suspected in 10 others.
Significant progress has been made in the past 10 years in knowledge of Buruli
ulcer, investments in related research, control of the disease, and improvement
of tools for case diagnosis and development of treatment protocols. Substantial achievements have been made in diagnosis, treatment, immunology and epidemiology. Despite these achievements, little is known about the exact mode of transmission of the disease, and there is no simple diagnostic test usable in the field.
The use of antibiotics has revolutionized treatment and contributed to reducing the need for surgery by half. However, efforts are still needed to develop simple diagnostic tools usable in the field as well as disability prevention methods. The Global Buruli Ulcer Initiative has adopted the strategy recommended by WHO. The strategy is based on early diagnosis of the disease and the use of antibiotics for treatment upon the onset of the first signs by improving access to screening and case management at the most peripheral level of the health system.

Trachoma, caused by particular serovars of Chlamydia trachomatis, is the leading
infectious cause of blindness. Infection is transmitted within ocular and nasal secretions that are passed from person to person on fingers, fomites (such as clothing) and eye-seeking flies (particularly Musca sorbens)....
Ophthalmic infection is associated with an inflammatory conjunctivitis known as “active trachoma”. Repeated episodes of active trachoma can scar the eyelids. In some individuals this leads to trachomatous trichiasis (TT), in which one or more eyelashes on the upper
eyelid touch the eye. TT is extremely painful. It can be corrected surgically, but, if left untreated, may lead to corneal opacification, resulting in vision impairment and blindness.

Gambiense human African trypanosomiasis is a deadly infectious disease affecting West and Central Africa, South Sudan and Uganda, and transmitted between humans by tsetse flies. The disease has caused several major epidemics, the latest one in the 1990s. Thanks to recent innovations such as rapid di...agnostic tests for population screening, a single-dose oral treatment and a highly efficient vector control strategy, interruption of transmission of the causative parasite is now within reach. If indeed gHAT has an exclusively human reservoir, this could even result in eradication of the disease. Even if there were an animal reservoir, on the basis of epidemiological data, it plays a limited role. Maintaining adequate postelimination surveillance in known historic foci, using the newly developed tools, should be sufficient to prevent any future resurgence.

Yaws is a disfiguring non-venereal disease caused by infection with the spirochaete. Treponema pallidum subspecies pertenue which is closely related to the causative agent of syphilis and those of the other endemic treponematoses, bejel and pinta. The disease is endemic in certain areas of the World... Health Organization (WHO) African, South-East Asia and Western Pacific regions. Of the neglected tropical diseases identified for elimination and eradication, yaws is one of two diseases targeted for eradication. In 1949, the Second World Health Assembly adopted resolution WHA2.36, which addresses yaws, bejel and pinta as major public health problems that need attention.
